The zinc coating has a thickness lower than two micrometer and an alloy layer zinc-steel is present between the zinc coating and the steel.ブリュイネール,ポールブリュネール,エリクヴァンギール,フラン
fatigue resistance of the Cu–Cu joints is enhanced significantly. Failure analysis shows that cracks propagation was retarded in the Cu joints without the original bonding interface, and the electrical resistance of the joints did not increase even after 1000 cycles of TCT. Finite element analysis ...
Steels are heavily used in infrastructure and the transportation industry, and enhancing their fatigue resistance is a major challenge in materials engineering. In this study, by introducing a gradient microstructure into 304 austenitic steel, which is one of the most widely used types of stainless ...
The change in electrical resistance can be used as a measure of the apparent mechanical load in the elastic regime [15]. As soon as the first transverse cracks occur at strain levels of roughly 0.33%, the stress–strain curve declines, while the electrical resistivity Fatigue tests In order ...
Metallic materials, in general, have high notch sensitivity, so the fatigue resistance is strongly influenced by defects that act as stress raisers. Fatigue is in fact caused by the accumulation of damage at regions, e.g., notches and imperfections, which act as local stress concentrations; ...
A corrosion resistant alloy is provided which includes, in percent by weight: (a) 16 to 24% Ni; (b) 18 to 26% Cr; (c) 1.5 to 3.5% Mo; (d) 0.5 to 1.5% Si; (e) 0.001 to 1.5% Nb; (f) 0.0005 to 0.5% Zr; (g) 0.01 to 0.6% N; (h) 0.001 to 0.2% Al; (j) less ...
the material of the surface layer of the roll including a surface layer of the roll having excellent resistance to fatigue.A material of the surface layer of the roll made by centrifugal casting has a composition which includes, in a base in mass%, C: 2.3% to 2.9%, Si: 0.2% to 0.8%...
the depletion of energy substrates and accumulation of metabolic byproducts has been demonstrated to occur following an acute bout of resistance training; however, peripheral accumulation and depletion appear unlikely candidates to accumulate over time. A number of mechanisms may contribute to the developm...
They further attributed the improved fatigue resistance at high mean strain to purported higher fatigue resistance of the martensite phase (Pelton et al., 2008; Pelton, 2011). 3. Materials and experimental methods Fatigue test specimens were laser cut from Nitinol tube, with a 10 mm outside ...
Since more and more heavily loaded components, e.g., automotive engines and transmissions, are produced by PM methods, studying the fatigue behavior will be increasingly important as well as, based on the findings, improving the fatigue resistance. For the PM tool and aerospace materials, optimizi...
